Question

Car X and Y start at the same time at speeds of 12 kph and 16 knph. Find the distance between them after 3 minutes.
A. 300 m
B. 150 m
C. 180 m
D. 120 m​

Answer 1

Answer:

12><3=36

16><3=48

48-36= 12km

Answer 2

Answer:

200m

I think the options are A.200m

                                     B. 150m

                                     C. 180m

                                     D. 120m

instead of                      

A. 300 m

B. 150 m

C. 180 m

D. 120 m​     ****check the question properly*******          

Step-by-step explanation:

let speed be s , time be t and distance be d

s of X = 12km/h = (12 * 1000/60)m/min = 200m/min

s of Y = 16km/h  =  (16 * 1000/60)m/min = 800/3 m/min

if t = 3 min then d of X = 200m/min * 3min = 600 m

                                  Y = (800/3)m/min * 3min = (800/3 * 3)m = 800m

distance between them = Y -- X = 800m - 600m = 200m
